Abstract:
A switching device for an electrically driven curtain includes a contact system. The contact system includes at least one sliding contact and contact tracks, which are housed in a sleeve-shaped projection. The contact tracks are provided on a connection plate, which is electrically connected to an electric driving device. The position of the sliding contacts can be changed by the pivoting movement of a switching lever.
Abstract:
An actuating device for moving a barrier comprising a gear motor adapted to transmit a rotary motion to a tubular support, solidly connected to said barrier and rotating with respect to a fixed support.The actuating device comprises improved regulation means of the end of run positions of the gear motor, which are easily usable even by an unskilled user.
Abstract:
An obstruction detection system for motorized window shades is presented having a motor, shade material, a bottom bar, and a motor controller having a microprocessor. The microprocessor is configured to detect when an obstruction has been encountered when closing the motorized window shades. When an obstruction is detected, the microprocessor stops lowering the shade material and the bottom bar thereby preventing further damage or destruction. The system may also be used to report when an unexpected obstruction has been detected.
Abstract:
An assembly for closing an opening comprising a door panel adapted for sliding movement between an open position and a closed position, a first extendable member located at a first edge of the opening and extendable towards an opposed second edge of the opening, and a second extendable member located at the second edge of the opening and extendable towards the first edge of the opening, and wherein the door panel includes a stop member attached thereto and movable therewith, the location of the stop member defining the limit of movement of the first extendable member towards the second edge of the opening, and the limit of movement of the second extendable member towards the first edge of the opening.
Abstract:
A roll-up type industrial door including a flexible sheet or woven fabric forming a curtain for closing a door way having an upper end, a lower end and two opposite side edges. The sheet has a main area and elongate side edge sections that are thicker than the main area. A shoulder is formed where each side edge section meets the main area. A curtain winding mechanism is connected to the upper end of the curtain and is used to raise the curtain. A pair of spaced apart guide channels are also provided and the side edge sections are movable therein. Each guide has one or two elastic members which act as locking blades. The locking blades of each guide form an elongate slot that receives a side edge section of the curtain.
Abstract:
The invention relates to a shading device for an architectural opening comprising a shade, a drive unit for extending and retracting the shade between a first and second end position, a spindle, a first end stop, stationary connected to the spindle near a first end of the spindle and at least one travelling nut, movably arranged on the spindle and operatively connected to the drive unit so as to move towards, respectively away from the first end stop as the shade is extended, respectively retracted. The travelling nut is articulated in circumferential direction into segments, with at least two segments being detachably connectable to each other at one of their ends.
Abstract:
An actuating system for a window shade includes a suspension member, a casing having a fixed protrusion, a transmission axle disposed through the casing, a rotary drum arranged in the casing and rotationally coupled with the transmission axle, and an impeding part connected with the rotary drum and affixed with an end of the suspension member. The rotary drum is rotatable in a first direction for winding the suspension member, and in a second direction for unwinding the suspension member. The impeding part is movable relative to the rotary drum between a first and a second position, the impeding part when in the first position being movable with the rotary drum past the protrusion in any of the first and second direction, and the impeding part when in the second position being engageable with the protrusion to block rotation of the rotary drum in the second direction.
Abstract:
A garage door opening module is disclosed, the module comprises a power unit having a rotatable output drive, an endless transmission drive adapted to transfer movement from the rotatable output drive to a door drive, and a sensor mechanism positioned along the endless transmission drive and adapted to sense a transmission drive slack, the sensor mechanism adapted to stop the power unit when a transmission drive slack displacement threshold is reached. A method for actuating a garage door and a sensor module for preventing movements of an assisted garage door are also disclosed.
